The ruins of the once formidable castle of Beauraing loom out above the Park Castel Sainte-Marie. The castle dates from the 13th century and suffered heavy damages during successive battles and fires. It was nearly burnt to the ground in 1889 by a heavy fire. Since then, the castle has changed hands quite a few times, the former horse stables were recently converted into guestrooms and a restaurant, and one of the towers (Charles Quint or Kaiser Charles) is now a holiday cottage.
